These are Fred and Keener, two characters from her comic 'Trivially True', which is about... SCIENCE! (among other things.) You should definitely go and check it out, as well as Oly's fantastic illustration work.

Wanted to draw Fred since ~TheColosseum, haha. Buck teeth, giant hair, nosy face, big ears... my kind of character! Of course, Keener is just the best (also, the type of guy you should probably keep an eye on. Totally want that 'butt plug' sweater.)

They both look great in your style and I just love all those vibrant colours everywhere! And smart details like the TARDIS mug and that book and W00t and oh my the expressions! And how you draw faces and hands and, well, everything! I love it and it made my day (though I just woke up) and thank youuuuu!

And aw, the Colosseum. Good old times. Would be so cool to meet in an OCT some day except we both don't seem to have time for OCTs anymore these days.
